The invention discloses a steel structure connecting joint capable of releasing fire temperature deformation, which comprises a first steel structure component, a second steel structure component, a plurality of friction type high-strength bolts and a connecting plate, and is characterized in that the connecting plate is provided with a long elliptical bolt hole, and the long elliptical bolt hole comprises a bolt hole near end and a bolt hole far end; a plurality of friction type high-strength bolts are in friction type connection with the connecting plate, the first steel structure component and the second steel structure component, so that the first steel structure component and the second steel structure component are spliced together, and then the steel structure connecting joint is formed; under the fire working condition, the first steel structural component and the second steel structural component deform due to temperature, and the friction type high-strength bolt slides from the near end of the bolt hole to the far end of the bolt hole, so that the temperature deformation of the first steel structural component and the second steel structural component under the fire working condition is released; the steel structure connecting joint is easy to install and environmentally friendly, and can still meet the structural fireproof safety requirement under the designed fire working condition.
本申请公开了一种能够释放火灾温度变形的钢结构连接节点，包括第一钢结构构件、第二钢结构构件、若干个摩擦型高强螺栓以及连接板，其中，连接板上开设有长椭圆形螺栓孔，长椭圆形螺栓孔包括螺栓孔近端和螺栓孔远端，通过若干个摩擦型高强螺栓与连接板和第一钢结构构件、第二钢结构构件摩擦型连接，使得第一钢结构构件和第二钢结构构件拼接在一起，进而形成钢结构连接节点；在火灾工况下，第一钢结构构件和第二钢结构构件受到温度变形，摩擦型高强螺栓从螺栓孔近端朝向螺栓孔远端滑动，从而释放火灾工况下第一钢结构构件和第二钢结构构件的温度变形，该钢结构连接节点易于安装环保、并且在设计火灾工况下仍能够满足结构防火安全性要求。
